Abstract
The current surface water shortage due to drought is prompting industries in Peninsular Malaysia to explore alternative water resources (AWR). Tenaga Nasional Berhad (TNB)’s reliance on town water has increased the risk of interruptions in supply, exposing the plant to shutdowns and reduced generation capacity. Consequently, TNB requires alternative water sources to mitigate these risks. This study aims to assess the groundwater potential at the Kapar Power Plant in terms of volume and quality as an alternative resource. Hydrogeological and geophysical surveys were conducted to locate prospective groundwater and determine its characteristics. Specifically, 2-D Electrical Resistivity Imaging (ERI) and Induced Polarization (IP) surveys were carried out using the ABEM Terrameter SAS 4000 and the ES10-64 electrode selector. A total of five survey lines were established, revealing four potential groundwater locations. However, two locations were selected for further evaluation, with a total yield of 15.5 m³/hr. This study provides valuable insights into utilizing groundwater as a sustainable alternative water source for TNB, helping to ensure operational stability and reliability for the power plant.
